Benefits of technology

[0006]The present invention provides an engageable abutment against the defect of the conventional abutment, the engageable abutment is designed to have an engageable sleeve on a base; the engageable sleeve has three functions: 1. It is adapted to being formed thereover a contemporary tooth crown that can be used for waiting healing of gingiva. 2. It has the function of transfer copying, and can be taken out; when in cast making an eternal tooth crown, the eternal tooth crown can be directly shaped in the sleeve for the convenience of fast and accurate assembling of the eternal tooth crown on the base. 3. It can alternatively be provided thereover with an eternal movable artificial tooth. Therefore, the present invention has a plurality of functions beneficial to processing of a dental implant surgical operation.

Embodiment Construction

[0019]Referring to FIGS. 2-4, an engageable abutment 1 of the present invention mainly comprises a base 11, a sleeve 12 and a set of engaging mechanism, and is connected between an implant root 2 and a tooth crown 3.

[0020]The base 11 of the present invention has therein a through hole 111 for extending through of a screw 112, such as is shown in FIG. 2; the base 11 thus can be connected and locked on the top of the implant root 2, and a protruding portion 113 (referring also to FIG. 4) is formed above the implant root 2, the protruding portion 113 has on its lower end an embedding portion 114 to be embedded in the implant root 2. The sleeve 12 can be formed thereover an eternal tooth crown or a contemporary tooth crown and is slipped over the protruding portion 113 of the base 11. The set of engaging mechanism mainly includes a protruding ball 131 and at lease a recess 132, the protruding ball 131 is provided in the sleeve 12, for example, as shown in the drawing, it is provided in ...
